Macroscopic quantum self-trapping of an ultracold Bose-Fermi mixture in a double-well potential

Caballero Benitez, Santiago; Ostrovskaya, Elena; Gulacsi, Miklos; Kivshar, Yuri

Description

We study the macroscopic quantum self-trapping effect in a mixture of Bose-Einstein condensate (BEC) and quantum degenerate fermions, confined in a double-well potential with a variable separation between the wells. The fermions form a finite-size cloud that affects the static and dynamical properties of the BEC. In particular, our quasi-analytical and numerical analysis based on a mean-field model shows that the main features of macroscopic quantum self-trapping in a pure bosonic system are...[Show more]
